GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 408) = 16320
GCD(320, 408) = ( 320 x 408 ) / 16320
= 320 / 408
= 320
Step2:
LCM(8, 204) = 408
GCD(8, 204) = ( 8 x 204 ) / 408
= 8 / 204
= 8
Step3:
LCM(4, 258) = 516
GCD(4, 258) = ( 4 x 258 ) / 516
= 4 / 258
= 4
So, Greatest Common Divisor of 320, 408, 204, 258 is 2
